Mabhatiri e lithium akawanda anogona kubatanidzwa muzvikamu zvakasiyana kuti agadzire bhatiri, iro rinogona kupa simba kune mitoro yakasiyana-siyana uye rinogonawo kuchajwa nguva dzose nechaja inoenderana. Mabhatiri e lithium haadi chero sisitimu yekutarisira mabhatiri (BMS) kuchaja nekuburitsa. Saka sei mabhatiri ese e lithium ari pamusika achiwedzera BMS? Mhinduro ndeyekuti kuchengetedzeka uye kugara kwenguva refu.
Sisitimu yekutarisira mabhatiri BMS (Battery Management System) inoshandiswa kutarisa nekudzora kuchaja nekuburitsa mabhatiri anogona kuchajwazve. Basa guru re lithium battery management system (BMS) nderekuona kuti mabhatiri anoramba ari mukati memiganhu yekushanda yakachengeteka uye kutora matanho nekukasika kana bhatiri rega rega rikatanga kudarika miganhu. Kana BMS ikaona kuti voltage yakaderera zvakanyanya, ichabvisa mutoro, uye kana voltage yakanyanya, ichabvisa charger. Ichaongororawo kuti sero rega rega riri mupaketi riri pavoltage imwechete uye inoderedza chero voltage yakakwira kupfuura mamwe masero. Izvi zvinoita kuti bhatiri risasvike voltage yakakwira zvakanyanya kana yakaderera zvine njodzi.–izvo zvinowanzo kukonzera kutsva kwemabhatiri e lithium atinoona munhau. Inogona kutotarisa tembiricha yebhatiri uye kubvisa paki yebhatiri isati yapisa zvakanyanya kuti ibate moto. Nokudaro, sisitimu yekutarisira mabhatiri yeBMS inobvumira bhatiri kuchengetedzwa pane kungovimba nechaja yakanaka kana mashandiro akakodzera emushandisi.
Sei usingadaro?'Mabhatiri ane lead-acid anoda sisitimu yekutarisira mabhatiri here? Kuumbwa kwemabhatiri ane lead-acid hakubatidzi zvakanyanya, zvichiita kuti asabatire moto kana paine dambudziko rekuchaja kana kuburitsa. Asi chikonzero chikuru chine chekuita nemaitiro anoita bhatiri kana rachaja zvizere. Mabhatiri ane lead-acid anoumbwawo nemasero akabatana akatevedzana; kana sero rimwe riine chaji yakawanda zvishoma kupfuura mamwe masero, rinongorega magetsi achipfuura kusvika mamwe masero achaja zvizere, uku richichengetedza voltage inonzwisisika, nezvimwewo. Masero anobatirira. Nenzira iyi, mabhatiri ane lead-acid "anozvienzanisa" paanochaja.
Mabhatiri eLithium akasiyana. Electrode yakanaka yemabhatiri eLithium anochajwazve inonyanya kuve zvinhu zveLithium ion. Musimboti wayo wekushanda unoratidza kuti panguva yekuchaja nekuburitsa, maerekitironi eLithium anomhanya kumativi ese eelectrodes akanaka neasina kunaka kakawanda. Kana voltage yesero rimwe chete ikabvumidzwa kupfuura 4.25v (kunze kwemabhatiri eLithium ane voltage yepamusoro), chimiro cheanode microporous chinogona kuparara, zvinhu zvakaoma zvekristaro zvinogona kukura uye kukonzera short circuit, uye tembiricha ichakwira nekukurumidza, zvichizoguma zvaita kuti pave nemoto. Kana bhatiri reLithium rachajwa zvizere, voltage inokwira kamwe kamwe uye inogona kukurumidza kusvika padanho rine njodzi. Kana voltage yesero rimwe mubhatiri rakachajwa rakakwirira kupfuura remamwe masero, sero iri richasvika pavoltage ine njodzi kutanga panguva yekuchaja. Panguva ino, voltage yese yebhatiri harisati rasvika kukosha kwakazara, uye charger haizomiri kuchaja. . Naizvozvo, masero anosvika pavoltage ine njodzi kutanga anokonzera njodzi dzekuchengetedza. Naizvozvo, kudzora nekutarisa voltage yese yebhatiri rakachajwa hazvina kukwana kune makemikari eLithium. BMS inofanira kutarisa voltage yesero rega rega rinoumba bhatiri.
Saka, kuti pave nechokwadi chekuti mabheteri e lithium akachengeteka uye agare kwenguva refu, hurongwa hwekutarisira mabhatiri hwemhando yepamusoro uye hwakavimbika hweBMS hunodiwa zvechokwadi.
